Show us your Arb Diggers please.

Looks a lot more complicated than it needs to be ? At a guess, a pair do the hydraulic disengage when arm up, another pair do the 'don't start when arm down' bit, and the other seems to be an earth for some reason? I'd test the wires still attached to switch with a multimeter- you can see by the diagram that one pair should be open and one should be closed. If it's not doing this then switch is at fault- buy new swith and replace, using heat shrink crimps if yoInsert other media u don't want to be messing around with intermittent connections in the future.

Bingo!

what to do with yellow wire?

Hi Steve, I yellow wire is an earth so try earthing it to metal on the machine somewhere!

 

I dont think the switch is your problem if you are hearing the "click". Its most likely the pump drive. Try checking pressure with the machine running, or crack of a hydraulic line from the pump with the machine running. If there is no oil its the pump coupling.

Sorry, I’d like to think I do my bit when it comes to sharing information.

 

This one is different, it’s a straightforward heads up for guys to do their homework if thinking of any of the JCB Midi range as a carrier for a Shear.

I really rate them, but checkout the brochures and you’ll soon find the issue.

A solution is another thing altogether!

 

 

Eddie.

Well I’ve had a look, and for instance, the JCB 67c delivers 90lt @ 190 bar. The Kubota 57 does 76lt @ 206 bar. I must be missing something because I can’t see why the JCB might be considered lacking.

Try a CAT 308 v JCB 85z

 

Remember an Intermercato Shear will require 250 Bar.

The problem is the solution or lack of.

So which functions of the shear require the extra pressure, 190 to 250 bar?

There’s only a Cut function on most Intermercato.

190 Bar you won’t cut 4” material

Not a big problem if you fit an intensifier on that service then

[william127]

I need some advise with my little kubota kx36 - 3. 

Last Friday I went to use it and the arm and track functions were virtually dead. The blade and slew are working fine but when you try and use any of the arm functions I just get groaning noises! 

I have changed the hydraulic oil and filters, no change--I wasn't really expecting any as the blade and slew work but seemed a sensible start. 

Anyone know how I bleed the hydraulics on this machine? I did put a new hose on it a few weeks ago but it's done a couple of problem free days work since and I've never had to bleed it before. 

Its bound to be the highly expensive pump??, but any suggestions would be welcome!

Tell me about these “intensifiers” please?
